Could someone help me, please? I'm having a problem with TP-Link C7 router with OpenWrt version 18.06.1.
I am trying to setup GRE tunnel and configure based on openWRT documentation. But when I try to ping tunnel remote Endpoint, ICMP packets don't reach to my Router's Wan interface. Remote Endpoint tunnel is established correctly as I can see ICMP packets coming from remote endpoint to my WAN interface. but again they are not getting forward to GRE interface.
Below is my config for Router 1:
root@OpenWrt:~# ip route show default via 192.168.231.254 dev eth0.2 proto static src 192.168.230.25 10.1.1.0/24 dev gre4-mygre proto kernel scope link src 10.1.1.1 192.168.1.0/24 dev br-lan proto kernel scope link src 192.168.1.1 192.168.230.0/23 dev eth0.2 proto kernel scope link src 192.168.230.25 config interface 'mygre' option proto 'gre' option ipaddr '192.168.230.25' option peeraddr '192.168.230.226' option mtu 1500 config interface 'mygre_static' option proto 'static' option ifname '@mygre' option ipaddr '10.1.1.1' option netmask '255.255.255.0'
I don't see any packets from gre interface to wan interface. I am not getting what I am missing here.
